AD9641BCPZ-80

Analog To Digital Converters (ADC) Overview

The AD9641BCPZ-80 is a single-channel, 14-bit analog-to-digital converter (ADC) operating at an 80 MSPS sampling rate. It features a differential pipelined architecture with integrated output error correction logic and JESD204A coded serial digital outputs. The device operates from a single 1.8 V supply, consuming 238 mW at the specified speed. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 73.7 dBFS at 70 MHz input frequency and a Spurious-Free Dynamic Range (SFDR) of 94 dBc under identical conditions. The component supports flexible analog input ranges from 1.4 V p-p to 2.1 V p-p and includes a programmable internal voltage reference.

Analog To Digital Converters (ADC) Feature Summary

• JESD204A high-speed serial interface reduces board routing requirements and lowers pin count for receiving devices.
• Multistage differential pipelined architecture with integrated output error correction logic ensures high linearity.
• On-chip PLL multiplies the ADC sampling clock to produce the corresponding JESD204A data rate clock.
• Flexible power-down options allow significant power savings when desired.

Analog To Digital Converters (ADC) Applications

• Communications
• Diversity radio systems
• Multimode digital receivers (3G and 4G)
• Smart antenna systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BCPZ' against the manufacturer's current ordering guide to confirm package type and RoHS compliance status. Ensure the selected variant matches the required 80 MSPS speed grade rather than the 155 MSPS option. Confirm that the LFCSP-32 package dimensions align with your PCB footprint design guidelines before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring a single-channel 14-bit resolution with an 80 MSPS throughput rate. The device is suitable for designs needing a 1.8 V single-supply operation and JESD204A serial connectivity. Consider the thermal characteristics of the LFCSP package if operating near the upper temperature limits or in confined spaces without airflow.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD9641 family of high-speed analog-to-digital converters manufactured by Analog Devices.
